REI-,N FoR-GED CONCRETE a citizen of. the United States, residing at San Francisco, in the county of San Francisco and State Iof California, have invented new and useful Improvements in Reinforced Con- -crete Piles, Vof which the following is a specilication. l y .My invention relatesto .forrny part of a Wall. `Its o ject is topro'vi'de partly broken to vshowbond ol' sand and con# crete below mud-line.' l Fig. 3 is -a plan of t he 4 to lit a hole in the drive end of the shoe A.

In practioin my invention I'Iemplojf a wooden shoe of suitable length and diameter, tapered, preferably, at the lower' end A and shod with a metal point 2. This point is here shown as made top shape, with a stem 3 'The upper end of the shoe has a reduced an- Vnular part to telescope with a hollow stave-`- a seat for the cylinder When t e pile is driven cylinder 4 and has an annular ledge for the end of the cylinder to abut a ainst and form i into the soil. The cylinder 4, while it may be of any suitable material, is preferably huilt upof Wooden staves, which are held in lace by means of metal hoops or bands 5,

he shoe is fastened to the cylinder. by boltsl or other suitable securin means. The joints between the staves of t e cylinder and ,be-

.tween the cylinder and shoe are intended to be Water-tight, so that when the pile is submerged no water may penetrate to the in- The c linder` may be of any desired or required lle/n th. The shoe need ,only be of such lengt as isnecessary to furnish the proper amount' of stock to resist splintering or injury under the blows intended to be iven to the opposite end of the cylinder to rivethe pile to place.

I I the pile `desired. Externallythepile has the appearance of :a metal-hound pile. 'This hollow pile :is dii` ven into the soil to a suitable depth by any appropriate'means. Heretofore, as far as l j am aware it has not been os- Sible to drive successfully hollowV cyliners, which'may be one hundred feet or more in length, becau: e of the liabilit *to movement of one stave on another" and theA accidents likely to occur in striking soil which resistsene side of the cylf' .nder more than the other and 1n ldiameter ile with a .so id tapered meta -shod shoe can drive ri -ht down through the soil. withoutdanger ofgin'ury of 'any kind to the lower' end o thefcy inder,

For the purpose of'protectingvthe u per end ofthe cylinder from the hammer in driving Ifemploy-a cap'l consisting'of Aa heavy metal p late vto lit over the'c'ylinder and having a eep'annular' angle-iron flange 7 to fit snug withinthe-cylinder.v The..depth of the an e is such tli'at'vvhenv the hammer delivers 'its b owen-the cap the latter will be prevented from jum ing out and off of the cylinder. To the to o the plate 6 are bolted the hardwood tim ers'8, preferably arranged in two layers, onel crosswise of the other. The shock. of the hammer'ormonkey-is received directly on these timbers. The solid-metal plate presses'e ually on the ends of all the stav es, and `ast 1e other end of all the staves bears equally on the shoe the pile may be driven home with the' same facility as a solidA pile and without danger of injury to the cylinder.

VIn operation/et hollow ile which comprises es sentlally the assc'mbledpshoe and stave-cylinder is set upright, the cap' laced on the end of it and driven to lace'. he interior of allowed to set. To give rigidity and strength to this concrete column, I may employ one or more vertical reinforcing-rods 9, running lengthwise of the column. Before filling the cylinder with cement, in cabe I want areinforced pile, I place in the bottom of the cylinrunning onto sunken and hidden'broken piles.

`since the p aint of the'shoe presents a very pile can be driven IOO the cylinderis then lil ed with concrete and ,der a templet l0, cut round to fit the cylinder. This late has a series of holes 1 larranged in circ e or any other desired form,;nto which the ends of the rods 9 are inserted @and seated. The cement is then rammed in around the rods. From time to time during the iilling and ramming a templet is slippeddown overA ranged about three inches from the cylinder callyindestructible.

or s ell 4. If desired, the ends of' the rod may be secured to the templet 10 vbefore the latter is placed in the cylinder, all being lowered into the cylinder at the/same 'time and the cement packed in afterward. The column thus formed of iron and concrete is practically indestructible, except it shouldbe sub- -ected to some extraordinary lateral strain or shock. The outer wooden casing .may be eaten away or destroyed and still the inherfA 4 ent strengthy of the pile will remain undiminished. l j

This pile is'simple to make, and thecost is considerabl less than that of the ordinary concrete pi e and pier constructions. .As a driven pile the concrete column has a substantial support far down in. the sand or mud below the mud or air lines. The cylinder being closed at the lower end and water-tight before the cement or concrete is put in allwa-` ter and mud are excluded from the cylinder, so that the cement and concrete will set pro erly and not crumble. It is impossible to ave cement and mud bound together where hollow open-endedcylinders are sunk into the mud. The wooden casing,which.re mains above the' mud, will eventually be destroyed either through natural decay or by the action of the teredo and other marine pests; but that part of the cylinder and the shoe remaining in the mud or' otherwise thoroughly protected from the air and water is practi` In tact, where piles are driven a considerable distance-say sixty feet, more or less-into deep mud or other loose and uncertain strata for the purpose of securing a suitable anchorage I may tan-1p a considerable ortion of my cylinder below the mud-line wit sand and so save the ex ense of concrete, of course leaving ol' wit the sand a suificient distance, which may be five or ten feet, more or less, below the mudline, so that there is no danger by the washing away oi the mud around the pile of the wooden cylinder which surrounds the sand being exposed. The trouble with most concrete piles or piers heretofore has occurred at their mud-line, due to the unsuhstantialsuport of the-concrete column and the imperfect bond between the concrete and the rnud. Nith a pile of my construction the outer wooden shell is water-tight. It is possible that various modifications in my invention may be made without departing from the principle thereof, and I lo not wish to be understood as limiting myself to the specific construction as herein shown and described. f

Having thus described my invention, what I claim, and desire to secureby Letters Patent, is'

1. A. pile consisting of awooden stave-.cylinderprovided with a shoe havin an iron tip, and a lling of concrete in the cy inder.

2. A pile consisting'of a stave-cylinder provided with a shoe at one end, the interior of said cylinder rendered water-tight, a series of rods within the cylinder and extending lengthwise thereof, and a filling of concrete around said rods.

3. A. reinforced concrete pile-comprising a Wooden shoe portiontapered at one end'and a metal point, the opposite end ,j

provided with of said shoe reduced, a wooden stave-cylinder into which the reduced end of said shoe is l i fitted, metal reinforces extending len thwise of the pile within. the cylinder, and a iilling of concrete surroundin .said metal reinforces.

4. In a wharf or Iikeconstruction, a pile consisting of a wooden stave-cylinder having a shoe at one end and driven into the mud, a packing of sand orthe like in the bottom of the cylinder, and a filling of concretewithin the cylinder sunerposed on said acking of sand and extenL ing below the Inu -line.

5. In a wharf or like construction, astavecylinder provided with a tapered Wooden s oe at one end and driven into the mud, and a iilling of concrete for said cylinder extendinv below the mud-line.
